AI Technical Summary
The current USB interface has terminals that are too close together, which causes crosstalk, increases characteristic impedance, affects signal quality and stability, and cannot meet the user's testing requirements.
Design an electrical connector in which a protrusion is provided on the side of the metal housing facing the terminal. The area of the protrusion is larger than that of the terminal, thereby reducing the distance between the metal housing and the terminal, providing the estimated shortest return path, and reducing the characteristic impedance.
By reducing electromagnetic interference signals and lowering characteristic impedance, the accuracy and stability of signal transmission are improved, thus enhancing the user experience.
